• How to convert a script from youtube-dl

  16 janvier 2020, par danilshik

  There is a bash/batch file script :

  ffmpeg -i `youtube-dl https://www.twitch.tv/zero` -vf fps=fps=60, scale=1920x1080 -c:v libx264 -b:v 500k -preset superfast -c:a copy -f segment -segment_time 60 test.mp4

  The script is not mine, but it allows you to record video with a constant frame rate of parts. Unfortunately in cmd it does not work for me. Already tried everything, I do not know what the error is.

  I am getting No such file or directory.

  Tried 'youtube-dl https://www.twitch.tv/zero', the same error

  I tried "youtube-dl https://www.twitch.tv/zero", error : youtube-dl https://www.twitch.tv/zero: Invalid argument

  What am I doing wrong ? The author assures that he works on linux

  Update

  I tried ffmpeg -i $ (youtube-dl -f best -g https://www.twitch.tv/zero) .... The same error

  Update 2

  Why the video size exceeds 500 Mb ? What am I doing wrong ?

  
  

  Code

  cls && @echo off & setlocal enableextensions enabledelayedexpansion 
  
  set "_tag_00=https://www.twitch.tv/avagg"
  
  set "_tag_01=--ignore-errors --abort-on-error --ignore-config --flat-playlist --geo-bypass "
  
  set "_tag_02=--restrict-filenames --no-part --no-cache-dir --write-thumbnail --prefer-ffmpeg "
  
  set "_tag_03=--ffmpeg-location .\ --postprocessor-args  -i "%%(title)s.%%(ext)s" -vf fps^=fps^=60^,"
  
  set "_tag_04=scale^=1920x1080 -c:v libx264 -b:v 500k -preset superfast -c:a copy -f segment -segment_time "
  
  set "_tag_05=60 %%^(title^)s.mp4"
  
  
  
  youtube-dl "!_tag_00!" -f "bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best" -o "%%^(title^)s.%%^(ext^)s" !_tag_1!!_tag_2!!_tag_3!!_tag_4!!_tag_5!
  
  Pause

• Creating automated ffmpeg converter

  27 janvier 2019, par Jeffrey Moser

  I am trying to create an automated process using ffmpeg and am having issues understanding how to adapt the code to automator.

  The code works beautifully in the terminal, but requires each filename to me entered manually. I am trying to automate the process.

  for f in "$@"
  
  do
  
  
  
  FILE= "$f"
  
  OUT=${FILE/mp4/png}
  
  OUT_WIDTH=10800
  
  OUT_HEIGHT=3600
  
  
  
  eval $(ffprobe -v error -of flat=s=_ -select_streams v:0 -show_entries stream=height,width "${FILE}")
  
  IN_WIDTH=${streams_stream_0_width}
  
  IN_HEIGHT=${streams_stream_0_height}
  
  
  
   eval $(ffprobe -v error -of flat=s=_ -count_frames -select_streams v:0 -show_entries stream=nb_read_frames "${FILE}")
  
  IN_FRAMES=${streams_stream_0_nb_read_frames}
  
  
  
  W_TILES=$(bc <<< "(sqrt($OUT_WIDTH*$IN_FRAMES*$IN_HEIGHT/($IN_WIDTH*$OUT_HEIGHT))+3)")
  
  H_TILES=$(bc <<< "(sqrt($OUT_HEIGHT*$IN_FRAMES*$IN_WIDTH/($OUT_WIDTH*$IN_HEIGHT)))")
  
  
  
  W_SHRUNK=$(bc <<< "$OUT_WIDTH/$W_TILES")
  
  H_SHRUNK=$(bc <<< "$OUT_HEIGHT/$H_TILES")
  
  
  
  ffmpeg -i "${FILE}" -vf "hflip,transpose=cclock,scale=${H_SHRUNK}:${W_SHRUNK},tile=${H_TILES}x${W_TILES},transpose=clock,hflip,scale=${OUT_WIDTH}x${OUT_HEIGHT}" -an -sn -vsync 0 "${OUT}"
  
  
  
  
  
  done

  I expected the code to produce an image of every frame of the film. But instead I got a massive error message.

• How To Install FFMPEG on Elastic Beanstalk

  26 mars 2020, par Nick Lynch

  This is not a duplicate, I have found one thread, and it is outdated and does not work :
  Install ffmpeg on elastic beanstalk using ebextensions config.

  I have been trying to install this for some time, nothing seems to work.
  Please share the config.yml that will make this work.

  I am using 64bit Amazon Linux 2016.03 v2.1.6 running PHP 7.0 on Elastic Beanstalk
